Hello world. Looked at [Drill Construction Set] and youtube videos about the Open Source Blueberries.
Drill Notes
Seems like a good project for me to learn about power electronics, CAD and get started with prototyping. I have a Ryobi RCD1802 that I will use as inspiration and benchmark. Costs roughly $150 here in Norway including battery and a bag.
Battery pack
- Ryobi battery is 18V 2.5Ah = Five 18650 cells in series. Can just go for that.
- Challenge with 18650 is that a Battery Management System is basically mandatory for Li-ion, to not burn down all the Seed Eco homes.
